The Interactions between Polyphenols and Microorganisms, Especially Gut Microbiota

Polyphenols and health: Interactions between fibre, plant polyphenols and the gut microbiota

A high-fibre diet and one rich in fruit and vegetables have long been associated with lower risk of chronic disease. There are several possible mechanisms underpinning these associations, but one likely important factor is the production of bioactive molecules from plant-based foods by the bacteria in the colon. This links to our growing understanding of the role of the gut microbiome in promot...

The Reciprocal Interactions between Polyphenols and Gut Microbiota and Effects on Bioaccessibility

As of late, polyphenols have increasingly interested the scientific community due to their proposed health benefits. Much of this attention has focused on their bioavailability. Polyphenol-gut microbiota interactions should be considered to understand their biological functions. The dichotomy between the biotransformation of polyphenols into their metabolites by gut microbiota and the modulatio...

Interactions of black tea polyphenols with human gut microbiota: implications for gut and cardiovascular health.

Epidemiologic studies have convincingly associated consumption of black tea with reduced cardiovascular risk. Research on the bioactive molecules has traditionally been focused on polyphenols, such as catechins. Black tea polyphenols (BTPs), however, mainly consist of high-molecular-weight species that predominantly persist in the colon. There, they can undergo a wide range of bioconversions by...

Relationship between gut microbiota and type 2 diabetes

Diabetes is the most common endocrine disease following the spread of metabolic diseases worldwide. Diabetes is also the fifth leading cause of death in the world. Patients with type 2 diabetes account for about 90% of people with diabetes. Studies over the past years have shown a significant association between intestinal microbiota, intestinal dysbiosis, and metabolic syndrome. Changes in the...
